On July 23, 2021, the famous Japanese physicist and Nobel Laureate Toshiei Maskawa passed away

Bunkashi Gongyi: The "Kobayashi-Masochina Theory" proposed by him is a basic "standard theory" of elementary particle physics, which is generally recognized by global elementary particle physicists; they theoretically predicted the existence of 6 kinds of quarks, shocking physicists around the world; he did not have any study abroad experience, completely cultivated in Japan, because his English was very bad, because he hated English speech, he rejected all foreign academic conferences, if it were not for the 2008 Nobel Prize in Physics ceremony, He probably would never take a step out of Japan in his lifetime.

Toshiei Musagawa was born in Nagoya, Aichi Prefecture in 1940.

In 1958, he graduated from Nagoya Municipal Xiangyang High School (Nagoya Municipal Xiangyang High School).

He graduated from the Faculty of Science at Nagoya University in 1962.

When Toshiei Maskawa was in college, he encountered a very headache - his English score was the worst in the whole year. The English teacher also knocked on the table more than once and said to Toshiei Meskawa, "How can you be such a smart person, how can you not learn English well?" If your English has always been like this, how can you possibly study abroad, and how can you possibly read the English version of the course? ”

Toshiei Maskawa dreamed of studying at Cambridge University in the United Kingdom, and wanted to become a world-renowned physicist like Nobel.

His professor said to him, "Very likely. Because you don't have good English, you can't go outside to communicate with others academically; you don't have good English, you can't grasp a lot of new knowledge at once; you don't have good English..."

"I especially hate English. I don't speak English now. When I applied for a graduate school at Nagoya University, one of the subjects was German, and I turned in a white paper."

Maskawa was famous for handing over the white papers, and the professors in charge of reviewing the graduate school entrance examination at the time planned to judge Maskawa as unqualified. But Professor Maskawa, who once supervised him, said: "Maskawa is a promising student, and I hope to make him qualified." I will find a way to teach him German", Maskawa passed the exam. But he also did not learn German later.

In 1967, he was completed by the Graduate School of Science, Nagoya University.

In 1967, he became an assistant professor at the Faculty of Science, Nagoya University.

1970 Assistant, Faculty of Science, Kyoto University. His compatriot and apprentice Makoto Kobayashi also joined Kyoto University two years later, and they eventually chose the symmetry-breaking problem related to the origin of the universe and matter.

Toshihide Toshihide Mshikawa's modern theory of physics holds that at the time of the Big Bang more than 10 billion years ago, the same number of particles and antiparticles should be produced at the same time, and particles and antiparticles are the same in terms of mass, but opposite in terms of charge, etc. When the two meet, they will annihilate and release energy at the same time. But this is not the case, and scientists have not found the same amount of antimatter as large amounts of matter in the current universe.

In 1973, Makoto Kobayashi and Toshiei Mesokawa proposed the Kabibo-Kobayashi-Maskawa matrix (Kobayashi-Maskawa model) to explain the symmetry of charge symmetry in weak interactions. The "Kobayashi-Masuda theory" was proposed, which suggests that the reason for the above phenomenon is that the reaction decay rate of quarks is different. At that time, he and Makoto Kobayashi jointly published an article discussing symmetry breaking in the Japanese science journal Advances in Theoretical Physics - "CP Destruction in the Theory of Weak Interactions"

They also predicted the existence of 6 quarks. According to modern physical theory, quarks and the like are more fundamental units of matter than subatomic particles such as protons and neutrons. At the beginning of the predictions made by Makoto Kobayashi and Toshiei Toshihikawa, scientists had only discovered 3 kinds of quarks, so it has been difficult to prove their theory. In 1995, all 6 quarks were discovered. In 2001, Japanese and American scientists confirmed the "CP symmetry breaking" phenomenon of positive and negative particles composed of quarks, B mesons and anti-B mesons, thus demonstrating the "Kobayashi-Masokawa theory".

In 1976, he became an assistant professor at the Institute of Nuclear Research at the University of Tokyo.

In April 1980, he became a professor at the Institute of Physics, Kyoto University.

In 1985, he received the Japan Academy Award.

In November 1990, he became a professor at the Faculty of Science, Kyoto University.

He was awarded the Asahi Prize in 1995.

In April 1995, he became a professor at the Graduate School of Science, Kyoto University.

In April 1997, he was the director of the Institute of Basic Physics, Kyoto University (until March 1999).

In April 2003, he was a professor emeritus at Kyoto University and a professor at the Faculty of Science at Kyoto University.

In October 2004, he was the Director of Research Institute at Kyoto Sangyo University.

In October 2007, he was a specially visiting professor at Nagoya University.

In 2008, he was awarded the Order of Japanese Culture.

In 2007, he was awarded the European Physical Society's 2007 Prize for High Energy Elementary Particle Physics.

In 2008, Toshiei Makoto Makikawa won the Nobel Prize in Physics together with Makoto Kobayashi and Yoichiro Minami, who had become a U.S. citizen, so this year, it was actually three Japanese people who won the nobel prize in the same field at the same time, which was the first time in the history of the Nobel Prize. In addition, the Japanese scholar Shu Shimomura, who lives in the United States, also won the Nobel Prize in Chemistry in the same year.

In 2009, he became the director of the Kobayashi Maskawa Research Institute for Particles and Cosmic Origins at Nagoya University.

At 8:40 a.m. on July 23, 2021, Toshiei Mizekawa died of gum cancer in his jaw at his own home in Kyoto City at the age of 81.

Toshihide Maskawa, Name: Toshihide Maskawa, Born in Japan, Toshihide Maskawa, February 7, 1940-July 23, 2021. A prominent physicist.
